Product Description

Product Introduction:

Screws, like bolts, vary by use. They often don't need nuts, screwing into pre-threaded holes or forming threads in soft materials through self-tapping for fastening, connecting, or positioning.

Product Features:

Screw Core Classifications:

Machine Screws: Standard threads (metric/imperial), fit pre-threaded holes, fully/partly threaded for precision.

Self-Tapping Screws: Drill, tap, and push without pre-threaded holes. Subcategories:

Ordinary Self-Tapping: For plastics, wood, thin metals.

Self-Drilling: Drill tip for steel, no pre-drilling, boosts efficiency.

Wood Screws: Deep threads, large pitch, sharp teeth, strong wood lock.

Set Screws: Fix parts' positions, prevent slip. End shapes:

Tapered End: High lock force for hard surfaces.

Flat End: Large contact, no surface damage.

Concave/Cylindrical End: Positioning or shaft hole pressing.

Structural screws: High-strength, heat-treated, replace bolts for steel structures, fast install.

Key Characteristics:

Compared to bolts, screws have these distinct traits:

Tapping/Screwing: Forms thread fit with material, no nut needed.

Frequent Disassembly: Secures covers, panels, components needing frequent assembly.

Wide Size Range: From tiny precision to large self-tapping screws for buildings.

Functional Integration: Many screws drill, tap, lock, seal (e.g., with washers).

Substrate Requirements: Load capacity depends on substrate strength (plastics, wood, metal).

Typical Application Areas:

Screws fit almost all industrial and daily life sectors:

Electronics & Appliances: Miniature and self-tapping screws secure housings, boards, components. Use stainless or treated carbon steel.

Machinery and Automation: Ideal for panels, covers, sensors, guide rails, clamps, using hexagonal or pan head screws.

Construction and Decoration:

Drywall Screws: Specifically for attaching drywall to joists.

Structural Screws: Connect light steel and wood structures.

Self-Drilling Screws: Secure color steel plates and purlins.

Automotive Industry: Extensive use of self-tapping and special screws in interiors, wiring, electronics, and decor.

Furniture and Wood: Wood screws primarily connect wood and boards like particleboard.

Precision Instruments: Uses precise miniature machine screws with high material and tolerance standards.

Aerospace: High-strength, lightweight, corrosion-resistant titanium/alloy screws widely used.
